Hi Volkan,

A simpler approach (with no manual storing) may be achieved via the fix_route_dialog() [1]. You can use this function after a match_dialog() on the ACK.

Hi Adrian

You can use store_dlg_value() to save the values of parsed headers like Contact header $ct.fields(uri) and retrieve them later from $dlg_val variable

If you have configured a stateful proxy and have the dialog module loaded the dialogs should be matched automatically.
